Mobile Push character limitation
To ensure uniformity across all devices, avoid display problems and to obtain the best results on iOS and Android push campaigns, we suggest the following character count:
iOS | Android | |
|---|---|---|
Title | 25-50 characters | up to 65 characters |
Body | up to 150 characters | up to 240 characters |
Always ensure to test your campaigns on different devices and preview them on the display device in the campaign creation tool to ensure that it is presented as expected.
